The disadvantage of multiple file compression is that you need to decompress everything, even if you only need one file.

How do you calculate compression?

Compression ratio in engineering can be calculated by dividing the total volume of a system before compression by the total volume after compression. In computing, file compression ratios are calculated by comparing the original file size to the compressed file size.


What software can test the quality of a file compression?

There are many pieces of software that can test the quality of a file compression software. The file compression software itself can give a percentage of compression, as well as a verification of whether it is compressed properly. One can also check the 'checksum' of the file.

What file formats use lossy compression?

There are a ton. Most things that use wavelets to encode the data fall into this category. Often the same file format and "extension" can have multiple actual encoding mechanisms on the inside, so it might sometimes have lossy compression and sometimes not. Examples of file formats with lossy compression include mp3,jpeg and mpeg. Container formats like avi, and wma sometimes do and sometimes don't.

What are the advantages of compression?

Compressing files or images enables you to (sometimes dramatically) decrease the memory space that file will take up. Without going into to too much detail, it works by 'approximating' the information in the file, thereby lowering the detail and filespace. However, compression also reduces the quality of the file, possibly corrupting it if it is compressed too much!
